Why Choose the Pizzato SR BD42AN3 Safety Magnetic Sensor?
The Pizzato SR BD42AN3 is a robust coded magnetic safety sensor designed for non-contact monitoring of guards, doors and access panels on industrial machinery. As part of the Pizzato SR B coded magnetic safety sensor series, it provides reliable guard position detection without the mechanical wear associated with conventional contact-operated safety switches.
This sensor uses a coded magnetic operating principle with reed-contact switching and provides 1NC + 1NO contacts with the guard closed. Its durable technopolymer housing incorporates stainless steel fixing plates and provides IP67 and IP69K protection, making it suitable for demanding industrial environments where dust, moisture and contamination may be present.
The SR BD42AN3 is supplied with an integrated 3 m PVC cable and is provided without an actuator. Compatible Pizzato coded magnetic actuators can be selected separately, including versions providing nominal actuation distances of 5 mm or 8 mm, allowing the sensing arrangement to be configured for the machine application.
Key Advantages
- Reliable coded magnetic guard monitoring without mechanical contact.

Reliable Non-Contact Guard Monitoring for Industrial Machinery
Coded magnetic safety sensors such as the Pizzato SR BD42AN3 monitor the position of machine guards without requiring physical contact between the sensor and actuator. When the correct coded magnetic actuator is positioned within the sensor's operating range, the internal reed contacts change state, allowing the connected machine safety system to verify that the protective guard is closed.
The SR B series is designed for industrial safety applications where reliable operation, resistance to contamination and minimal mechanical wear are important. When paired with a suitable safety module and correctly designed safety architecture, the SR BD42AN3 can contribute to safety systems achieving high functional safety levels while providing dependable monitoring on frequently operated machine guards.
Typical Applications
- Machine guard and safety door monitoring.
- Industrial enclosure and access panel interlocking.
- Packaging and production machinery.
- Automated assembly and material handling equipment.
- Processing and washdown machinery.
- OEM machine building and industrial safety systems.
